Patented Nov. 7, 1944 UNITED STATES PATENT OFFICE 2,362,024 OVER LL BUCKLE Edward F. Pavek, Stillwater, Minn.

Application August 25, 1941, Serial No. 408,205

7 Claims.

My invention relates to an improvement in overall buckles, wherein it is desired to provide a buckle which will permit overall straps to be easily adjusted and which are easily detachable when the garments are Washed.

In overalls it is usual practice to provide buckles siderable time for the salesman who sells the overalls, as he must make adjustments while fitting the overalls to the wearer.

It is the object of the present invention to provide an overall buckle which will clamp the overall straps in any desired adjustment and which may be removed by a simple action. Accordingly when it is desired to change theadjustment of the overall straps, the straps are folded to the desired adjustment and the buckle again snapped to clamp the straps in this adjusted position.

A feature of my invention relates to the simple adjustability of the snap, which permits the removal of the snaps and the button engaging loops which might otherwise be injured in the washing or drying process.

A further feature of the present invention resides in the provision of a. loop of wire, or the like, which overlies one surface of the straps,

and a flat spring clamping member which en-v gages against the opposite surfaces of the straps to clamp the straps between the loop and the spring strip. The spring strip is pivotal with respect to the loop and engages the loop under spring tension to the end thereof opposite the pivotal attachment. By merely springing the end of the spring strip free from the end of the loop, the buckle may be disconnected.

A further feature of the present invention resides in the embossing of a name or any desired advertising matter on the spring strip in such a manner that the inner surface of the spring strip presents an irregular surface to bear against the straps to prevent slippag of the straps through the buckle.

A further feature of the present invention.

These and other objects and novel features of my invention will be more clearly and fully set forth in the following specification and claims.

In the drawing forming a part of my specification:

Figure 1 is a perspective view of a portion of a pair of overalls showing the adjustment loops in place thereupon.

Figure 2 is an elevation view of the buckle removed from the straps.

Figure 3 is a top plan view of the buckle shown in Figure 2.

Figure 4 is a front elevation view of the buckle in position upon an overall strap.

Figure 5 is a rear view of the buckle in place upon an overall strap.

Figure 6 is a sectional view through the buckle, the position of the section being indicated by theline 6-6 of Figure 2.

Figure '7 is a sectional view vertically. through the buckle and strap, the position of the section being indicated by the line 1-1 of Figure 4.

Figure 8 is an elevation view of a modified form of construction.

The overalls A may be of any desired or preferred type. usually provided with a bib ID, to which is attached a pair of buttons H. The buttons II are designed for engagement 'by button engaging loops l2 which are held within a fold provided by doubling the ends of the supportingstraps I3.

1 The straps [3 are doubled through the buckles l2 and the free end [4 of the strap I3 is folded to the rear of the body of the strap, as indicated in Figure 7 of the drawing. The buckles B hold the strap in folded relation and may be released in a simple manner to change the adjustment of the straps l3.

Each buckle B includes a loop l5 which includes a pair of transversely extending substantially parallel bars [6 and I1, and a pair of. substantially parallel loop ends [9 and 20. Connecting the transverse bars 16 and I! and the loop ends I9 and 20, I provide outwardly bowed arcuated portions 2| which permit free movement of the straps and free pivoting of the two parts of the buckles.

Pivoted to the loop end 20, I provide a spring plate 22. The spring plate 22 is bent to form a substantially cylindrical'barrel or journal 23 encircling the loop end 20 and to provide pivotal attachment between the spring plate 22 and the loop l5. At the opposite end or free end of the spring plate 22, I provide an arcuated channel member 24 designed to engage about the loop end IS with spring tension. A lip 25 at the extreme end of the plate 22 form a means whereby the spring plate may be engaged by a finger and unsnapped from the loop end IS. The channel shape of the plate member 24 closely encircles On the rear surface of the loop I5, I provide a series of projections or irregularities 26 which engage against the strap 13 to prevent the strap from sliding through or past the loop l5. In order to hold theplate 22 from slipping with respect to the strap 13, I provide in preferred form,

an embossed name or symbol indicated in the drawing by the numeral 21 in which the letters project inwardly toward the loop I and engage against the surface of the strap l3 to prevent slipping of the strap.

In order to more securely lock the plate 22 in clamping position, I provide a recess 29 in the channel end M of the strip 22, and in the end 19 of the loop I provide an outward projection or lug designed to extend into the pocket or recess 29. This outward projection 30, when engaged in the recess 29, looks the plate 22 from pivotal movement with respect to the loop I5.

In the operation of the buckle B, the strap I3 is folded to include the button engaging loop l2 and the free end M of the strap I3 is folded up against the inner surface of the strap IS. The clamp B is then applied in place with the loop l5 overlying the outer surface of the strap and the plate 22 underlying the inner surface of the strap. The two parts of the buckle B are then clamped together by pressing the end l9 of the loop l5 into the channel-shaped end 24 of the spring plate 22, the outward projection 30 engaging in the recess 29. When locked in this position, the strap I3 is securely clamped between the two parts of the clamping device and held from slipping by the inward projections 26 on the loop l5 and the forward projections 21 on the plate 22.

In the modified form of construction illustrated in Figure 8 of the drawing, the operation is similar to that previously described in conjunction with the buckle B. I have found that the overall straps [3 are sometimes formed with inturned hemmed edges, making the edges of the strap much thicker than the center portion of the strap. With these thickened straps, it is impractical to use the buckle B without using a'relatively narrow strip 22. For overall straps which are provided with inturned marginal edges, so as to provide thickened longitudinal strap edges, I form the buckle C, illustrated in Figure 8 of the drawing.

The buckle C is formed with a loop 3| which is identical in form and shape to the loop .15. A strip 32 is provided with a journal 33, similar to the journal 23 and which encircles one end 34 of the loop 3 l The other end of the strip 32 is provided with a channel 35 which engages over the end 36 of the loop 3|, the channel end 35 to accommodate a projecting lug 39 on the end 36 of the loop 3|. A name, such as 49, may be embossed into the strip 32.

Notches 4! are provided in the end of the strip adjacent the journal 33 and notches 42 are provided in the strip 32 adjacent the channel end 35. As a result, the thickened edges of the overall straps may engage in these notches without decreasing the force which the spring strip 32 has upon the center portion of the overall strap. Thus lip portions 43 are provided on the spring strip 32 between the notches 4| and the notches 42 to engage against the strap under spring tension.

In accordance with the patent statutes I have A recess 31 is formed in.

ill

described the principles of construction and operation of my buckle, and while I have endeavored to set forth the best embodiment thereof, Idesire to have it understood that this is only illustrative of a means of carrying out my invention and that obvious changes may be made within the scope of the following claims without departing from the spirit of my invention.
